IMPROVEMENT IN APPARATUS FOR AITACHING PUMPS T0 BUNGS OF BARRELS.

Specification forming part of LettersPatent N0. 40.082, dated September22, 1863.

To all whom t may concern.-

Be it known that l, FRANCIS A. PRATT, of the city and county ofHartford, in the State of Connecticut, have invented a certain new anduseful Fastening for BarrelPumps; and I do hereby declare that thefollowing` is a full, clear, and exact description thereof, ref erencebeing had to the accompanying drawings, making part of thisspecification, and to the letters ot' reference marked thereon, inWhich- Figure l represents a cross-section of a bar rel with myinvention applied thereto as a means of fastening for a. rotary pump.Fig.

2 is a side elevation of part of the suctionpipe of a pump and theapparatus for fastening the pipe to a barrel. Fig. 3 is a plan view ofthe same; and Figs. 4, 5,6, 7, and 8 illustrate an invention for which Iam about to apply for separate Letters Patent.

Similar letters of reference denote the same part in the several gures.

My invention relates to an'apparatus by which a portable pump may besecured to a barrel.

Previous to my invention much inconvenience and waste of time and laborhave been experienced in the use of barrelpumps on account of theinsuiicient means which have been employed to secure the pump to thebarrel, and in consequence of which the pump has been so loosely heldthat it is liable to change its position with every effort to work it. A

lt is the object of my invention to furnish a device by which a pump maybe rigidly fastened to a barrel, in such a manner as to permit the rapidand advantageous working' of the pump, and which may be adjustable tovarious sizes of barrels.

To these ends my said invention consists in the employment, incombination with the rigid suction-pipe of a portable pump, of a saddleor crab, a hooked bolt for clamping the crab to a barrel, and a setscrewfor clamping the suction-pipe to the crab, or their respectiveequivalents, constructed, arranged,

and operating substantially in the manner hereinafter clearly set forth.

To enable others skilled in the arts to make and use my invention, Iwill proceed to a description thereof.

In Figs. l, 2, and 3, to which the following description refers, a isthe rigid suction-pipe of a rotary pump, B. c is a four-footed crab, ofwhich d d d d are the legs or feet. The hub of this crab looselyencircles the suctionpipe a of the pump. bis a bolt, the lower end ofwhich is formed into a hook,f. Its upper part is threaded, and passesthrough a hole made in the hub of the crab o, parallel with its axis.The nut g of this bolt b bears on the top of the hub of the crab. h isabinding-screw, which is screwed into one side of the hub of the crab cand reaches through the side, so that its point may be made to pressagainst the suction-pipe a, and thus firmly clamp the suction-pipe tothe crab c.

To make use of the apparatus which I have described, the hooked end f ofthe bolt I is thrust into the bung-hole of a barrel, and is hooked underthe edge of the hole. (See Fig.

l.) The crab c, supported on its four feet, which straddle thebung-hole, is iirmly clamped down onto the surface of the barrel E byscrewing down the nut g of the bolt b. The suction-pipe a of the pump isnow thrust through the hub of the crab down as far into the barrel as itmay be desired, and the binding-screw h is then turned so as to clampthe pipe securely to the crab, by which means the pipe a, andconsequently the pump B, are immovably secured to the barrel, and cannotbe drawn out nor in any way displaced bythe act of pumping.

The threaded part of the bolt b should be of sufficient length to adaptthe apparatus for use on barrels having different thickness of staves.

The feet d of the crab c may be made very much shorter than represented,as they need only be long enough to support the crab steadily upon thecurved surface of the barrel, or a curved square plate-like a saddle-abined, arranged, and operating to secure a barrel-pump to a barrelsubstantially in the `manner hereinbei'ore described.

In testimony whereof I have hereunto set my hand this 24th day ofAugust, 1863.
